A new analysis reveals something that we already sensed from far away, but when shown graphically it is very visible and easy to understand. How much power do the latest gaming APUs from Intel and AMD consume? Which is more energy efficient speaking? And of course what is the difference in watts between them? By answering these questions we will arrive at the conclusion of efficiency, so let’s go there.
Efficiency in Intel vs AMD, new fight between Cezanne and Rocket Lake for PC

Anything that saves us in watts every day is important since electricity is at its highest historical price since we have records. That is why having a more efficient CPU is not silly and to compare we have three great exponents such as Ryzen 7 5700G (Cezanne), the i7-11700 (Rocket Lake-S) and the Ryzen 7 4750G (Renoir).
The comparison and graph that we are going to see measures the relationship between the power consumption of each APU / CPU, the frequency and the score that has been obtained in Cinebench R20, where all the power states are logically in PL2 and PTT.
The system and its conditions as well as its configuration are described at the bottom of the graph itself, where the most curious thing is undoubtedly the configuration of the fan and its RPM / º C curve, since 100% is only achieved when the processor it has reached or exceeds 80ºC.
AMD beats Intel with lower power consumption and higher performance
There is not too much discussion here as you can see. The table is really very graphic, where we already see that at the same frequency AMD is clearly superior to Intel. Starting with laptop consumption with ultrabook figures such as 15 watts We see that AMD not only achieves a higher frequency, but that the performance is much higher.
But what is most striking is undoubtedly that Intel has a performance decline, when instead in consumption it is higher even reducing the frequency. From that jump, the data skyrockets and the curve becomes more diagonal, mainly between 2.7 GHz and 3.1 GHz.
In contrast, AMD is not only more efficient, but also gets a much higher amount of available frequencies than Intel, allowing it to better manage power regardless of processor status. The curve is much smoother, although the rise is greater at the end of it, but above all we can see is that the consumption jumps are much smaller than those of Intel even though it also obtains frequency jumps of 100 MHz at some points.
Renoir, on the other hand, offers much worse data with a curve that is much more vertical, which shows AMD’s architectural leap with Cezanne and Zen 3. The data does not lie: 85 watts versus 140 watts, better energy distribution by jumps in MHz, better performance compared to its rival and all at an exactly the same price (i7-11700K to compare just as both processors are unlocked, the 11700 is 60 euros cheaper and it’s locked on overclock). Therefore, with an AMD CPU you will use less electricity and pay less on your electricity bill.
